Nikon's Coolpix 2100 instruction book says you can delete all photos on your compactflash card in one felled swoop, but I sure can't find where that command is! The dedicated "trash" button just deletes one at a time, but obviously this is a drag when you've downloaded all your shots to your computer and you're ready to dump them all from the card. Can anybody point me to the steps to get to "delete all"?

Try formatting the card. It doesn't matter what brand of camera or card you are using, the best way to delete is to format the card. If you delete individual images on the camera, you stand a chance of corrupting the card and you'll have to format it anyway.

Download all the pictures, including the ones you don't want, and delete the bad ones on the computer. In the meantime, after the download is done, format the card IN THE CAMERA. This will always be the safest way to proceed.

I have the Coolpix 2200 with an SD card, but maybe the answer is the same.

I first have to hit the "Play" button wich lets me see the pictures I've taken. Then when I hit the "Menu" button, I get options including "Delete" (selected images), "Delete All" (requires confirmation, i.e. ""Sure?"), etc. Without first hitting the "Play" button, I don't think I can get to the "Delete All" command.
